"Speed Bleeder" are often crap.
Even if might work now, they hold more brake fluid that draws water then that causes corrosion problems.
If you replace calipers then expect to use a Quart of fluid to flush and fill the system.
If you "pedal bleed" then note can "ruin" the MC w/ dirt/corrosion problems.
